BAND-WHEEL.

Application filed November 29,1918. Serial No. 264,547.

To all whom it mag concern: I

'Be it known thatI, CLYDE S. WVRIGHT, a citizen of the United States, residing at Toledo, inthe county of Lucas and State of Ohio, have-invented new and useful Improvements in Band-'Wheels, of which the following is a specification.

My invention relates to band-wheels or the like, for example, such as are usedwith well-drilling apparatus.

Band-wheels for well-drilling rigs are sometimes very large and heavy, their diam-' eterbein-g ten feet or more and their weight They are often mounted on frames whose distance from the band-wheel shaft to the bottom of the frame is less than the radius of the wheel, so that it is practically necessary to remove the wheel from the shaft when a drilling rig with such a wheel is moved from place to place, because the portion of the wheel projecting below the frame prevents a firm seating for the'rig. To place one of these large heavy band-wheels on its shaft is usually a very diflicult job, particularly when the fit of the wheel-hub on the shaft is close. It is I the principal obj ect of this invention to provide a wheel and'its mounting so that the wheel may be readily and easily assembled with its mountingand removed therefrom.

Referring to the accompanying drawing, Figure 1 is a side elevation of thecentral part of a band-wheel made in accordance with my invention, a portion of the rim being also shown, and Fig. 2 is a central vertical section of Fig. l.

On the drawing, 1 designates the shaft on which the band-wheel is mounted. On one end of this shaft I secure the metal sleeve or hub 2 in any practicable manner, as by the key 3. The hub has the annular flange 4 preferably at right angles with the hub and the shaft. The rear face of the flange is provided with suitable braces. while the front face is preferablyflat. The hub has two different diameters in front of the flange 4. The largest diameter is next to the flange as shown at 5. This diameter need extend only a short distance, where it is connected to the portion 6 of smaller diameter by the inclined annular shoulder 7 the inclination being toward the center of the hub and the outer end thereof. The outer end of the portion 6 is provided with the outwardly tapering annular shoulder 8 inclined preferably at the same angle as the shoulder 7.

The wheel comprises'the rim 9, the central portion 10 opposite the-flange 4, and the spokes 11 which connect the rim and central portion. This wheel is made of wooden pieces designed andassembledfin a'm'anner well known. I

On the rear face of the'portion 10 is placed the steel plate 12 having a central opening which fits the larger diameter 5 of the; hub; and'on the front faceof the portion 10 I place a steel plate-13 having an opening fitting-the smaller diameter 6 of the hub. The plates 12 and 13 and the central portion 10 of the wheel are tightly clamped together by the bolts 14, having their heads preferably in the'h'oles 15 whichpreferably' extend entirely through the flange 4; The wheel is secured to the flange 4: by the bolts 16- which extend through the flange, the plates 12 and 13, and the wheel portion 10. The heads of the boltsj'16' rest preferably against the rear face-of the flange A: while the nuts 17 are screwed on the bolts against the outer face of the plate 13; I

To assemble the wheel on the hub 2, the wheel is placed with the larger end of the central opening in line witlr-theshaft. v As the larger end of the opening is larger than the portion 6 of the hub- 2, v the wheel is readily moved over the portion 6 to the base of the shoulder 7 atwhich time the inner edge of the plate 13 is at or on the base of the shoulder 8. By applying force to the wheel it may be readily slid on the wheelcentering shoulders 7 and '8 until the plate 13 is on the hub-portion 6, and the plate 12 is on the hub portion 5 and against the flange l. The said force is readily supplied by inserting the bolts 16 and screwing up the nuts 17 against the plate 13, which easily move the wheel from the bases of the. shoulders 7 and 8 to its final place and secure it there. These bolts may be replaced by shorter ones, if desired. The outer shoulder 8 may be omitted.

By driving against the heads of the bolts 14 or against the plate 12 through the openings 15, the wheel may be moved or started away from the flange 4. v

I claim:

1. A wheel with a central opening having different diameters, a hub seated in the opening the wheel to the flange.

2. A wheel with a central opening having different diameters, a hub seated in the opening and having difl'erent diameters corresponding in number and size to those of the said opening, an inclined centering shoulder connecting the adjacent diameters of the hub, a second centering shoulder at the outer end of the hubportion having the smallest diameter, a flange on the hub, and means securing the Wheel to the flange.

' 3. A wheel with a central opening havin difi'erent diameters, a hub seated in the open ing and having diiferent diameters corresponding in number and size to those of the said opening, an inclined centering shoulder connecting the adjacent diameters of the hub, a second centering shoulder at the outer end of the hub portion having the smallest diameter, the consecutive shoulders being separated by distances corresponding approximatelyto those between the consecutive diameters of the said opening, a flange on the hub, and means securing the wheel to the flange.

4. A wheel with a central opening having diflerent diameters, a hub seated in the opening and having difl'erent diameters correspondingin number and size to those of the said opening, an inclined centering shoulder connecting the adjacent diameters of the hub, a flange on the hub, and means coopcrating between the wheel and hub for forcing the wheel over the centering shoulder andfor preventing the wheel from moving on the hub.

- 5. A wheel having a central opening,

plates secured to opposite sides of the wheel shoulder connectin the two diameters of the hub, and means securing the wheel on the hub. T

6. A wheel having a central opening, plates secured to opposite sides of the wheel and having openings concentric with the central opening, the opening in the plate on the outer side of the wheel being of less diameter than the opening in the other plate, a hub seated in the opening and having two diameters corresponding to the openings in the plate, an inclined centering shoulder connecting the two diameters of the hub, means securing the plates to the wheel, and means securing the wheel on the hub.

7. A wheel having a central opening, plates secured to opposite sides of the wheel and having openings concentric with the central openlng, the opening in the plate on the outer side of the wheel being of less diameter than the opening in the other plate, a hub seated in the opening and having two diameters corresponding to the openings in the plate, the portion of the hub with the larger diameter being short and the portion with the smaller diameter being substantially the distance between the rear faces of, the plates, an inclined centering shoulder connecting the two diameters of the hub, and means securing the wheel on the hub.
